附图说明
图1是本发明控制车辆行驶的方法较佳实施例的流程示意图;
图2是本发明控制车辆行驶的装置较佳实施例的功能模块示意图。
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。
具体实施方式
应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
本发明实施例的解决方案主要是:获取车辆的位置信息;获取车辆所在车道的图像信息;对车道的图像信息进行解析,得到车道的车道线的位置信息;对车辆的位置信息及车道线的位置信息进行分析,得到车辆的一侧与同侧车道线的距离值a;将车辆的一侧与同侧车道线的距离值a与预先设定的车辆的一侧与同侧车道线的距离范围值b进行比对,根据比对结果判断车辆是否偏离车道; 若判断结果为车辆偏离车道,则提示用户车辆偏离车道。本发明能防止车辆在行驶过程中偏离车道,此外,还可以通过对车道线的类别进行识别,在车辆偏离车道时对用户进行提醒,提高了车辆的行驶安全性。
具体地,参照图1所示,本发明较佳实施例提供了一种控制车辆行驶的方法,该方法包括:
步骤S1,获取车辆的位置信息;
在本实施例中,可以通过GPS定位器或者移动运营网络基站定位器等来获得车辆在所在车道上的位置信息。此外,作为另一种实施方式,还可以通过摄像装置等获取车辆所在周边区域的图像信息,通过图像信息获取车辆在所在车道上的位置信息。
步骤S2,获取车辆所在车道的图像信息;
在本实施例中,可以通过图像获取模块获取车辆所在车道的图像信息,具体实施时,可以在车辆的车头、车尾或者车的两侧安装车载摄像头,采集车辆所在车道的图像信息。
步骤S3,对车道的图像信息进行解析,得到车道的车道线的位置信息;
通过车载摄像头获取到车辆所在车道的图像信息后,可以利用数学模型并结合现有的图像处理的技术对图像信息进行解析,得到车道的车道线的位置信息。
步骤S4,对车辆的位置信息及车道线的位置信息进行分析,得到车辆的一侧与同侧车道线的距离值a;
以图像信息为例,在得到车辆在所在车道上的位置信息,以及车辆所在车道的车道线的位置信息后,根据上述两种位置信息,可以得到车辆的一侧与同侧车道线的相对距离值a。
步骤S5,将车辆的一侧与同侧车道线的距离值a与预先设定的车辆的一侧与同侧车道线的距离范围值b进行比对,根据比对结果判断车辆是否偏离车道;
车辆在道路上行驶的时候,车辆的一侧与同侧车道线应当保持一定的距离范围值b,如果通过比对得到车道的一侧与车道线的距离值a位于距离范围值b以内,则判断车辆没有偏离车道,否则,判断车辆偏离车道,进入步骤S6。
其中,可以根据经验值预先设定该距离范围值,该设定的过程可以是由车辆自身通过软件设置并存储到本地,也可以是由工作人员根据经验值设定好之后存储到车辆本地。
步骤S6,若判断结果为车辆偏离车道,则提示用户车辆偏离车道。
本实施例中,可以通过语音播报的方式或者通过在车载显示器上显示的方式或者其他方式来提醒用户车辆偏离车道。
本实施例通过上述方案,获取车辆的位置信息;获取车辆所在车道的图像信息;对车道的图像信息进行解析,得到车道的车道线的位置信息;对车辆的位置信息及车道线的位置信息进行分析,得到车辆的一侧与同侧车道线的距离值a;将车辆的一侧与同侧车道线的距离值a与预先设定的车辆的一侧与同侧车道线的距离范围值b进行比对,根据比对结果判断车辆是否偏离车道; 若判断结果为车辆偏离车道,则提示用户车辆偏离车道,由此能在车辆偏离车道时对用户进行提醒,提高了车辆的行驶安全性。
进一步地,在上述步骤S3,对车道的图像信息进行解析,得到车道的车道线的位置信息的步骤中包括:
对车道的图像信息进行解析,得到车道的车道线的类别信息。
为了提高车辆行驶的安全性,通常会将车道分成不同的种类,比如行车道、超车道、应急车道等,并根据需要将车道采用虚线或者实线、双实线等进行划分。为了进一步提高车辆的行驶安全性,本实施例通过对车道的图像信息进行解析之后,得到车道的车道线的类别信息,以判断车辆偏离车道时,能否变更车道。
若通过上述步骤S5进行比对的结果判断为车辆偏离车道,且车道线的类别为实线或者双实线等禁止车辆变道的标志线,则提示用户车辆偏离车道,并提示用户纠正车辆行驶方向。
若通过上述步骤S5进行比对的结果判断为车辆偏离车道,且车道线的类别为虚线,则提示用户车辆偏离车道,并提示用户是否需要变更车道。
本实施例通过上述方案,能防止车辆在行驶过程中偏离车道,此外,还可以通过对车道线的类别进行识别,在车辆偏离车道时对用户进行提醒,提高了车辆的行驶安全性。
另外,在步骤S1,获取车辆的位置信息的步骤之前可以预先设定车辆安全行驶的时候,车辆的一侧与同侧车道线的距离范围值b,其中,距离范围值b包括端点值b1及端点值b2,端点值b1为车辆安全行驶的时候车辆的一侧与同侧车道线的最小距离值,端点值b2为车辆安全行驶的时候车辆的一侧与同侧车道线的最大距离值。最小距离值b1及最大距离值b2可以通过经验来进行设定。
车辆在道路上行驶时,有可能向车辆的一侧偏离车道,也有可能向车辆的另外一侧偏离车道。
若将车辆的一侧与同侧车道线的距离值a与预先设定的车辆的一侧与同侧车道线的距离值范围b进行比对,比对结果为a<b1,则判断车辆向车辆一侧偏离车道;若比对结果为a>b2,则判断车辆向车辆的另外一侧偏离车道。
若比对结果为b1≤a≤b2,则判断车辆没有偏离车道。
综上所述,本发明控制车辆行驶的方法通过上述方案:获取车辆的位置信息;获取车辆所在车道的图像信息;对车道的图像信息进行解析,得到车道的车道线的位置信息;对车辆的位置信息及车道线的位置信息进行分析,得到车辆的一侧与同侧车道线的距离值a;将车辆的一侧与同侧车道线的距离值a与预先设定的车辆的一侧与同侧车道线的距离范围值b进行比对,根据比对结果判断车辆是否偏离车道; 若判断结果为车辆偏离车道,则提示用户车辆偏离车道,由此能防止车辆在行驶过程中偏离车道,此外,还可以通过对车道线的类别进行识别,在车辆偏离车道时对用户进行提醒,提高了车辆的行驶安全性。
鉴于上述控制车辆行驶的方法,如图2所示,本发明还提供了一种控制车辆行驶的装置。该装置包括定位模块10、图像获取模块20、图像解析模块30、分析模块40、判断模块50及提示模块60。其中:
定位模块10用于获取车辆的位置信息;
在本实施例中,可以通过GPS定位器或者移动运营网络基站定位器等来获得车辆在所在车道上的位置信息。此外,作为另一种实施方式,还可以通过摄像装置等获取车辆所在周边区域的图像信息,通过图像信息获取车辆在所在车道上的位置信息。
图像获取模块20用于获取车辆所在车道的图像信息;
在本实施例中,可以通过图像获取模块20获取车辆所在车道的图像信息,具体实施时,可以在车辆的车头、车尾或者车的两侧安装车载摄像头,采集车辆所在车道的图像信息。
图像解析模块30用于对车道的图像信息进行解析,得到车道的车道线的位置信息;
通过车载摄像头获取到车辆所在车道的图像信息后,可以利用数学模型并结合现有的图像处理的技术对图像信息进行解析,得到车道的车道线的位置信息。
分析模块40用于对车辆的位置信息及车道线的位置信息进行分析,得到车辆的一侧与同侧车道线的距离值a;
以图像信息为例,在得到车辆在所在车道上的位置信息,以及车辆所在车道的车道线的位置信息后,根据上述两种位置信息,可以得到车辆的一侧与同侧车道线的相对距离值a。
判断模块50用于将车辆的一侧与同侧车道线的距离值a与预先设定的车辆的一侧与同侧车道线的距离范围值b进行比对,根据比对结果判断车辆是否偏离车道;
车辆在道路上行驶的时候,车辆的一侧与同侧车道线应当保持一定的距离范围值b,如果通过比对得到车道的一侧与车道线的距离值a位于距离范围值b以内,则判断车辆没有偏离车道,否则,判断车辆偏离车道,进入步骤S6。
其中,可以根据经验值预先设定该距离范围值,该设定的过程可以是由车辆自身通过软件设置并存储到本地,也可以是由工作人员根据经验值设定好之后存储到车辆本地。
提示模块60用于当判断结果为车辆偏离车道时,提示用户车辆偏离车道。
本实施例中,可以通过语音播报的方式或者通过在车载显示器上显示的方式或者其他方式来提醒用户车辆偏离车道。
本实施例通过上述方案,定位模块10获取车辆的位置信息;图像获取模块20获取车辆所在车道的图像信息;图像解析模块30对车道的图像信息进行解析,得到车道的车道线的位置信息;分析模块40对车辆的位置信息及车道线的位置信息进行分析,得到车辆的一侧与同侧车道线的距离值a;判断模块50将车辆的一侧与同侧车道线的距离值a与预先设定的车辆的一侧与同侧车道线的距离范围值b进行比对,根据比对结果判断车辆是否偏离车道;提示模块60在判断模块50判断车辆偏离车道时,提示用户车辆偏离车道,由此能在车辆偏离车道时对用户进行提醒,提高车辆的行驶安全性。
进一步地,图像解析模块30还用于对车道的图像信息进行解析,得到车道的车道线的类别信息。
为了提高车辆行驶的安全性,通常会将车道分成不同的种类,比如行车道、超车道、应急车道等,并根据需要将车道采用虚线或者实线、双实线等进行划分。为了进一步提高车辆的行驶安全性,本实施例通过图像解析模块30对车道的图像信息进行解析之后,得到车道的车道线的类别信息,以判断车辆偏离车道时,能否变更车道。
若通过判断模块50判断为车辆偏离车道,且图像解析模块30通过对图像解析出车道线的类别为实线或者双实线等禁止车辆变道的标志线,提示模块60则提示用户车辆偏离车道,并提示用户纠正车辆行驶方向。
若通过判断模块50判断为车辆偏离车道,且图像解析模块30通过对图像解析出车道线的类别为虚线,提示模块60则提示用户车辆偏离车道,并提示用户是否需要变更车道。
本实施例通过上述方案,能防止车辆在行驶过程中偏离车道,此外,还可以通过对车道线的类别进行识别,在车辆偏离车道时对用户进行提醒,提高了车辆的行驶安全性。
另外,作为对本较佳实施例的一种改进,还可以设置设定模块,设定模块用于预先设定车辆安全行驶的时候,车辆的一侧与同侧车道线的距离范围值b,其中,距离范围值b包括端点值b1及端点值b2,端点值b1为车辆安全行驶的时候车辆的一侧与同侧车道线的最小距离值,端点值b2为车辆安全行驶的时候车辆的一侧与同侧车道线的最大距离值。最小距离值b1及最大距离值b2可以通过经验来进行设定。
车辆在道路上行驶时,有可能向车辆的一侧偏离车道,也有可能向车辆的另外一侧偏离车道。
若判断模块50将车辆的一侧与同侧车道线的距离值a与预先设定的车辆的一侧与同侧车道线的距离值范围b进行比对,比对结果为a<b1,则判断车辆向车辆一侧偏离车道;若比对结果为a>b2,则判断车辆向车辆的另外一侧偏离车道;若比对结果为b1≤a≤b2,则判断车辆没有偏离车道。
综上所述,本发明控制车辆行驶的装置通过上述方案:定位模块10获取车辆的位置信息;图像获取模块20获取车辆所在车道的图像信息;图像解析模块30对车道的图像信息进行解析,得到车道的车道线的位置信息;分析模块40对车辆的位置信息及车道线的位置信息进行分析,得到车辆的一侧与同侧车道线的距离值a;判断模块50将车辆的一侧与同侧车道线的距离值a与预先设定的车辆的一侧与同侧车道线的距离范围值b进行比对,根据比对结果判断车辆是否偏离车道; 提示模块60在判断模块50判断结果为车辆偏离车道时,提示用户车辆偏离车道,由此能防止车辆在行驶过程中偏离车道,此外,还可以通过对车道线的类别进行识别,在车辆偏离车道时对用户进行提醒,提高了车辆的行驶安全性。
